Answer:
- Firstly , See the attached picture! :) I splitted the provided figure into two rectangles i.e namely small rectangle & big rectangle !
- Find out the area of small rectangle having length of 14 ft & width of 12 ft :
- Find out the area of big rectangle having length of 20 ft and width of 19 ft :
- Now , Add the area of small rectangle & area of big rectangle :
- ✺ WORK HARD! So that tommorrow , your parents can be recognized by your name!
♡Hope I helped! ツ
☼Have a wonderful day / evening !☃

In the picture which one are you doing because I am confused
Answer:
2.28 miles
Step-by-step explanation:
1 foot = 0.00019miles
12000 feet = x miles
Cross multiply
x = 12000 x 0.00019
x = 2.28 miles
Answer:
$3.17
Step-by-step explanation:
Since it wanted you to write three dollars ($3) and 17 cents ($0.17) using the dollar symbol, $3.17 would be the correct answer.
Answer:
a) p-hat (sampling distribution of sample proportions)
b) Symmetric
c) σ=0.058
d) Standard error
e) If we increase the sample size from 40 to 90 students, the standard error becomes two thirds of the previous standard error (se=0.667).
Step-by-step explanation:
a) This distribution is called the <em>sampling distribution of sample proportions</em> <em>(p-hat)</em>.
b) The shape of this distribution is expected to somewhat normal, symmetrical and centered around 16%.
This happens because the expected sample proportion is 0.16. Some samples will have a proportion over 0.16 and others below, but the most of them will be around the population mean. In other words, the sample proportions is a non-biased estimator of the population proportion.
c) The variability of this distribution, represented by the standard error, is:
d) The formal name is Standard error.
e) If we divided the variability of the distribution with sample size n=90 to the variability of the distribution with sample size n=40, we have:
If we increase the sample size from 40 to 90 students, the standard error becomes two thirds of the previous standard error (se=0.667).
